摘　　要：单通道冷绝缘高温超导电缆的铜骨架直径的主要决定因素为超导电缆的短路热稳定性、载流能力以及交流损耗。除此之外,由于超导层带材的排布方式间接地影响了超导电缆的载流能力、交流损耗以及超导电缆的机械强度,因此在设计时带材排布方式也是必须要考虑的设计铜骨架直径的因素。文中综合考虑各因素之间的重要程度,提出了设计单通道冷绝缘高温超导电缆铜骨架的设计流程,并以110kV/3kA的高温超导电缆为例进行了设计计算。The overall diameter of a single cold dielectric HTS cable＇s former was determined by the heat steady - state of short - circuit current, the ability of transport current, AC loss and so on. In addition, because the tapes arrangement means in- directly affected the current carrying capacity of superconducting cable, AC loss and the mechanical strength of the superconduct- ing cable, therefore the tapes arrangement was the major factor which we should take into account. This work summarized a varie- ty of factors that impacted the former＇s design and provided the calculation of the coefficient of thermal stability and the design process of former, and taking the 110kV/3kA HTS cable as an example to show the design calculations.
